The common household chemical hydrogen peroxide, also made naturally by living cells, appears to be involved in regulation of circadian rhythms, according to a new study. If a circadian rhythm is like ...

Chemical engineers have developed a sensor that lets them see hydrogen peroxide inside cancer cells and determine whether they are responding to drugs that affect redox signaling. MIT chemical ...

In an oxygen-depleted environment, endothelial cells initiate an adaptive pattern of synthesis, which may enable them to survive hypoxic crises. Using high-resolution two-dimensional gel ...

Photodynamic treatment of cancer is based on administering an initially inactive substance that is only activated in the ...
